"Generally accepted" knowledge doesn't translate to truth.
You seem to be lowering your standard of evidence because you simply want to believe there is life outside this solar system. I think you're being a hypocrite.
Either there is evidence, or there isn't. You hold me to this standard, and I am simply doing the same to you.
John Lennox once said something I totally agree with: "2+2=4, but knowing that has never put 4 pounds into my pocket".
No one is claiming that there most definitely IS life out there, just simply pointing out the possibilities.
Its like me saying that it is probably raining somewhere on Earth right now. Do I have any evidence, no I do not and lets pretend that I can't possibly get any evidence. I have not stated a belief nor have I taken a leap of faith, I am simply making an educated guess based off of what I currently know.
You are trying to claim that me saying that it is likely raining somewhere on Earth right now is along the same lines as you saying that there IS a god. The two statements couldn't be more different.
As I said, I am not closed to the idea, but speculations and probabilities cannot be tested in this regard, so they mean nothing.
Wait, are you saying that something that can not be tested is meaningless? Do you really wish to go down that road Rob?
I mean, what if someone suspected I robbed the Comerica bank yesterday. I mean, we have evidence that people rob banks, so is speculation alone enough to get me arrested and tried?
No it isn't but I have yet to see this wildly held definitive belief in the scientific community that life does as an absolute fact exist somewhere else in the universe that you seem to believe exists. Could you please give me 4 or 5 examples, at the very least, so that I can at least join you in saying that they are stating something as a fact that they can not possibly prove (yet or perhaps ever)?
And as I said Rob, we aren't that special. We are made up of the
most common elements in the universe. Every last element in your body used to be part of a star, a star that died long ago spewing the elements that would eventually make you, me, the planet and everything else. We are quite children of the stars so to say, made up of actual stardust. Pretty cool isn't it? As far as "just right", the planet has been drastically warmer and colder in the past yet life has thrived so that "razors edge" that you speak of isn't as close as you may think. Regardless, just because it is "just right" for us doesn't mean its the only possible condition in which life could evolve (nor does it mean the opposite). We have exactly ONE data point, who the hell knows what other conditions life might be able to develop in?
Another fun fact my friend, life has and continues to thrive in the harshest environments earth has to offer. We have found life in places that we previously KNEW that life couldn't possibly exist, yet it does. If life can thrive in the most extreme conditions our planet has to offer (which can get pretty damned extreme) who is to say that other life needs our "goldilocks" environment? Again, this is not me saying that I have faith that other life exists, it is me pointing out what might be possible.
